本文分别制备了乙烯基酯树脂(VE)与火焰法碳纳米管(F—CNT)以及十六烷基胺改性火焰法碳纳米管(H—CNT)的复合材料,并用扫描电子显微镜(SEM)和动态力学分析仪(DMA)研究了复合材料的结构和性能.实验结果表明,同化学气相沉积制备的碳纳米管(C—CNT)相比,F-CNT与H—CNT在乙烯基酯树脂中具有较好的分散性,同时复合材料的玻璃化转变温度Tg和储能模量E’与CNT的种类及质量分数密切相关.
Employing the carbon nanotubes synthesized by diffusion flame method (F-CNT) and those functionalized with n hexadecylamine (H-CNT), F-CNT/vinyl ester resin(VE) and H-CNT/VE composites had been fabricated by in-situ polymerization, respectively. The structure and properties of these composites were studied by scanning electron microscopy (SEM) and dynamic mechanical analyzer (DMA). The experiment results indicate that F-CNT and H-CNT show a better dispersion slate comparing with the carbon nanotube synthesized by(TVD (CCNT). In addition, both glass transition temperatures (Tg) and storage modulus (E') of the composites are closely related to the species and weight percentage of carbon nanotubes.
